Overview

The HXZK-CFJZ differential reference station (also known as a reference receiver) is a fixed device used to improve satellite positioning accuracy. Based on a known location, it identifies issues such as atmospheric and ionospheric interference and orbit errors by comparing the received signal with the expected signal, and then transmits correction information to mobile terminals in the area to assist in centimeter level positioning. This device adopts IP66 protection level and industrial grade design, supporting 365 days; #215; 24-hour continuous work, suitable for harsh environments ranging from -40 ℃ to+80 ℃. Capable of tracking all constellations in Q direction, able to receive BDS, GPS, GLONASS

HXZK-CFJZDifferential reference stationsystem architecture

The differential positioning system accurately collects satellite positioning error information through benchmark stations deployed on the ground, forming differential data. The data is transmitted via the network to the central server for processing and integration. Subsequently, the server broadcasts the processed high-precision differential data in real-time to various user terminals through broadcast links (such as mobile communication networks or dedicated data links). After the positioning terminal equipped on the user end receives and applies this differential data, it can effectively correct the common errors in its own positioning results, thereby significantly improving the positioning accuracy and ultimately achieving centimeter level high-precision positioning. To meet the diverse requirements of application scenarios, positioning terminals provide various design options, such as vehicle mounted integrated devices, portable handheld devices that are easy to carry, and wearable card and helmet terminals, ensuring that users can flexibly choose the most suitable terminal equipment according to their actual work environment.
